As
the explained in Sumaṅgalavilāsinī,
the jasmine bud colour and golden powder colour
can be easily found and identifed but for the Mutta
colour it is quite confusing.

Mookda
in Thai comes from the word Muttā
in
pali, in Thai dictionary it is said mookda can be
pearl or can mean the name of one precious stone
which is smoky colour. Hence, somebody identifies
it as moonstone. If we consider it to be
pearl, we can hardly find them.

However
if we consider it as "the moonstone which has already
burnished" it can be possible that mookda
may not be pearl but may be the Buddha's relics
which are white as has and pearl like tones. The
same applies to the golden powder colour, any yellow
colour type can be classified into this group.

The
floating relics

The
ancient teacher said the Buddha's relics and his disciples'
relics which are not too big can be floated. When floating
on the surface of water there appears a depression to support
them. Moreover a radius can appear around the Buddha relics.

Whenever
floated, the Buddha's relics can attract and float together
even if they are far from each other. For this reason, there
is the story talking about anybody who pays the regular high
respect to the Buddha's relics, they can attract pieces to
be in one place together.

There
is the prohibition from the teacher not to test the Buddha’s
relics by floating as it means to look down on our Lord Buddha.

*refer
to the article of Khunying Sureephan Maneewat about herself
to apologize to the Lord Buddha after her intention to test
by floating them.

Note
: About the year 2003, an elder friend visited our website
and told about her case when she took the Buddha's relics to bath.
She put them into the prepared water, they sank directly into the
bottom of the container. Her friends who investigated around asked
for the floating as being told before. Then, she made a wish and
suddenly the Buddha's relics floated up on the surface of water.
